I think most of the Mikrotik deployments I've seen for 44net (or
HamWAN) have either been with the RB2011, the newer RB3011, or the
RB750 options. I have a CCR1016 and it's way overkill for anything
just 44net. Unless you're planning on running a full BGP router and
terminating dozens of VPNs you should be fine with any of the other
series' CPU and RAM options.
I think the RB750GR3 is the best bang for your buck if you don't need
POE or SFP.

The RB960PGS is probably the best bang for your buck if you do.

Someone with actual experience on those platforms should weigh in though.
